548242 Bore 333.375 Mm, Tapered Roller Bearings, Double Row With Extended Cone
The 548242 Rolling mill bearings are mainly suitable for applications such as floating ends that bear medium to heavy radial loads and need to accommodate shaft thermal expansion, or roll necks that need to bear combined radial and axial loads, as well as gear drives.
The 548242 bearing is a Tapered Roller Bearings, double row with extended cone with an inner diameter of 333.375 mm , an outer diameter of 469.9 mm, a width of 166.688 mm. Bearing steel rings, Bearing steel rolling mlement. It primarily bears Radial and axial loads, its static radial rated load is approximately 5400000 N. Open type, together determine its load-bearing capacity, rotational accuracy, and applicable working conditions.
548242 bearings ( 333.375 mm x 469.9 mm x 166.688 mm) have the advantages of Extremely high load-bearing capacity and rigidity, and are therefore widely used in the Hot rolling, cold rolling, and wire rod mills.
